NVIDIA Spectrum-4 SN5600 128-Port 400GbE Ethernet Switch

The NVIDIA Spectrum-4 SN5600 is a 128-port 400GbE Ethernet switch engineered as a high-radix spine fabric for modern AI and machine learning infrastructure. Launched in Q2 2023, it delivers non-blocking switching capacity of 51.2 Tbps with ultra-low latency and deterministic performance, making it the preferred choice for hyperscale cloud operators and financial institutions constructing cost-effective alternatives to proprietary InfiniBand networks. The architecture leverages NVIDIA Spectrum-4 ASIC technology with native RoCEv2 (RDMA over Converged Ethernet) offload capabilities, enabling lossless Ethernet operation and GPU-to-GPU communication at line rate across thousands of compute nodes.

Ideal for

• Large-scale distributed AI model training across GPU clusters with 1000+ accelerators requiring sub-microsecond latency and lossless transport
• High-frequency trading and quantitative finance infrastructure leveraging RDMA for ultra-low-latency data center interconnect
• Cloud provider spine fabrics consolidating multiple application workloads (inference, batch processing, analytics) on unified Ethernet infrastructure
• Hyperscaler data center expansion with disaggregated rack-scale systems requiring high-radix, low-cost fabric alternatives to custom silicon
• Multi-tenant GPU utility services and inference platforms demanding deterministic performance isolation and QoS guarantees
• Research computing and scientific simulation workloads requiring massive collective communication bandwidth (AllReduce, AllGather operations)
